Too complicated code for generating a random string?

auto randomString = iota(10).map!(_ => letters[uniform(0, $)]).array;

Bearophile has long asked for a one-parameter uniform(n) that does what 
uniform(0, n) does. Perhaps this provides a good supporting argument. 
With that enhancement:

auto randomString = iota(10).map!(_ => letters[uniform($)]).array;

I expect this to be fast and only allocate once.
